Ae92 4age into ae82 seca

[Corollawagon90]

Was wondering if anyone has done this swap. Really needing some help with the ae82 and ae92 dash wiring integration. Was thinking of maybe just swapping the whole ae92 dash harness over as well. Then wiring it into the ae82 stuff like the cluster, heater controls , heater fan, etc

I haven't done it, but I'd get both wiring diagrams first. You will only need to take the 4AGE loom and ECU with it, and then power a few wires from the chassis to the ECU.  Odd things will be coil power, alty, starter setup if the chassis is different, but it has to be easier than 4AGE to replace a 4K.

I've done an early 4AGE into both an AE82 and AE86 with 4AC's.  Notwithstanding the fact that the AE92 has later sensors with different plugs, I would suggest swapping over the dash, engine bay charge and engine loom entirely.  Easier to adapt minor components to the newer loom.
